Improved weather-strip for doors



l UNITED STATES PATENT OFFICEo JOHN YOUNGBERG, OF GALVA, ILLINOIS.

IMPROVED WEATHER-STRIP FOR DOORS.

Specification forming part of Letters Patent No. 39,983, dated September 15, 1863; antedated December 8, 1861.

-Galva, in the county ot Henry and State of Illinois, have invented a new and useful Imlprovement in Ieather-Strips for Doors; and

I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawing, making a part ot' this specication, and to the letters ot'ret'erence marked thereon.

The object ot this invention is to close the joint between the bottom of the door and the sill; and it consists of a vertical plate riveted to a piece of indiaerubber, which is secured to the sill and extended across the bottom of the door on the inner side in such a manner that hejoint is kept tight when the door is closed, and when the door is opened the strip ispressed back and down, and retained in Va horizontal position under the door until the closing of the latter permits it to rise and assume the the vertical position in which it closes the joint,

To enable others` skilled in the art to make and use my invention,I will proceed to describe its construction and operation.

The drawing represents a door with the weather-strip of my invention attached. The lines in black show its position when the door is closed, and those in red show its position when the door is open.

lhe inner sill is somewhat lower than the outer to permit the easy passage of the door over the Weatherstrip when it is laid ida-t on the sill, and it has a groove, a a, into which the edge of a piece of vulcanized indiarulober, b I), extending across the width ot' the door-frame, is secured by screws or cement. The upper edge of the india-rubber is riveted to a sheet-metal clamp, c c, which extends across the door. The ends ofthe indiarubber are fastened to the frame at d and e, which causes the weather-strip to retain a vertical position, pressing against the bottom ot' the door, when it is not otherwise and forcibly pressed back and down by the opening of the door. As will be particularly seen in the red lilies, the outer part of the lower edge ofthe door atj'is chamt'ered away for the purpose ot' easily pressing the weatherstrip down when the door is opened. The buttons g and hnlay be turned over the strip when it is desired to keep it down with the door closed.

The operation ot' the invention is simple. The strip is opened by the opening ofthe door, which it presses down and causes it to lie tlat on the sill, and the elasticity of the india-rubber causes it to rise immediately on the closing of the door, and keeps it pressed tightly on the joint ofthe door and sill. As it is placed on the inner side, it catches any water that may be admitted by the imperfections of the door, and it is not liable to injury by the accumulation of ice in sleety weather, and being of vulcanized india-rubber it is not affected by heat or cold in the ordinary variations of temperature.

I claim as my invention and desire to secure by Letters Patent- The construction of a weather-strip, as described, of india-rubber, stiiened by a plate in such a manner that it will be opened by the opening of the door and closed by its own elasticity when the door is closed.
